em code example

Example 1: em

/*1em = 16*/
/*Best solution*/
body
/*THis will set the body font to default size which is commonly 16px*/
{
  font-size: 100%
}
/*Now you adjust element font-size according to the body*/
p
{
  font-size: .8em
}

Example 2: emacs

$ brew cask install emacs

Example 3: em

$ elm diff Microsoft/elm-json-tree-view 1.0.0 2.0.0
